"During a question-and-answer session after his keynote speech at the 67th International Astronautical Congress in Guadalajara, Mexico, Musk revealed his desire to name at least one SpaceX ship The Heart of Gold.
“We’re thinking about names. The names thing is really hard,” Musk said, “And the name of the first ship that goes to Mars not the name of the whole ship line necessarily but the first ship that goes to Mars … my current favorite is Heart of Gold.” Mirroring the sense of whimsical humor from the novel, Musk emphasized he liked the idea of the name because “it’s driven by infinite improbability because I think our ship is also extremely improbable. I like the infinite improbability drive.”
